On September 24, 2026, Invest Acquisition Corporation, a Cayman Islands exempted company (the “Company”), held an extraordinary general meeting of its shareholders (the “Meeting”). Shareholder approval of the matters set forth below was obtained at the Meeting by the holders of approximately 99% of the issued and outstanding voting shares of the Company, without proxy solicitation. An Information Statement relating to the Meeting was furnished to shareholders pursuant to Section 14(c) of the Securities Exchange Act of 1934, as amended, and Rule 14c-1 thereunder.

At the Meeting, the shareholders approved certain amendments to the Company’s Second Amended and Restated Memorandum and Articles of Association as described below.

Amendment to Amended and Restated Memorandum and Articles of Association - Extension of Business Combination Deadline

The amendment deletes Article 49.5 of the Second Amended and Restated Memorandum and Articles of Association in its entirety and replaces it with a new Article 49.5 reflecting the Extended Date of December 17, 2029 (the “Charter Amendment”). The Extension was approved with 10,625,000 votes in favor, representing approximately 99.76% of the outstanding ordinary shares, and no votes against.
